The national success of the Randy Rogers Band probably stumps every bean-counting major-label executive in Nashville. Here’s a group from San Marcos, Texas, that doesn’t wear cowboy hats, doesn’t dress in fashionable duds, doesn’t make the high-profile TV rounds, and doesn’t even have the clout to snag a mainstream country radio hit.

Yet the last three RRB discs have all charted in the Top 10 of Billboard’s country-albums list. The band even cracked the Top 10 of Billboard’s pop-albums countdown with 2010’s Burning the Day. Nothing like a Texas outfit defying conventional Nashville wisdom.

Trouble, the Randy Rogers Band’s sixth studio effort, is likely to follow suit. And it should. It’s an impressive record that craftily balances Lone Star attitude with Middle America sensibility. The production by Jay Joyce is clean without turning slick, allowing Rogers and his bandmates Geoffrey Hill, Jon Richardson, Les Lawless and Brady Black to be heard sans unnecessary sonic clutter. These guys even have the honor of working with highly esteemed guests Willie Nelson, Ray Wylie Hubbard and Gary Allan.

One of the best cuts on the disc, “Fuzzy,” showcases Hubbard on electric guitar and background vocals. I love the psychedelic tremolo guitar that blazes during the chorus. The tune, about a trashy-boozy night that renders our protagonist more than a bit hazy, is one of those hollering-at-the-top-of-your-lungs anthems. It’s got real kick.

“Trouble Knows My Name,” a similar wild-night story song, features Nelson taking one of the verses and harmonizing on the chorus. Written by Rogers and Hill, “Trouble Knows My Name” revs its way to a kicking finale in which Rogers tells us about being on tour in Missoula, Mont., with “country music’s brightest star,” he sings. Well, things got out of hand and by the next morning “he barely posted bail.” Hmm, who could that be?

On a more emotional note, Rogers explores the addictive nature of love during “If I Had Another Heart,” a great midtempo number co-written by fellow Texan Radney Foster and containing the memorable tag line: “If I had another heart, I’d let you break that one too.” Later “Never Got Around to That,” which Rogers co-wrote with the revered tunesmith Dean Dillon, vividly details the pain of a man afraid of making a lasting commitment.

There are other gems here — namely the dark, sobering “Shotgun,” penned by Richardson, and the highway breezy “Flash Flood,” which includes Allan singing background vocals.

Trouble, boasting way-cool fingerprints CD-cover artwork, is further proof that the Randy Rogers Band should be making records in the splashy Nashville biz. They have the best of both worlds, access to primo studios and all that inherent Texas grit.

Fittingly, the RRB boys celebrate the release of Trouble in the core of Cowtown. Join the group for a CD-release-party performance May 2 at 8 p.m. at Billy Bob’s Texas, 2520 Rodeo Plaza, Fort Worth. General admission is $15, and that gets you a copy of Trouble. To buy your ticket, go to billybobstexas.com.
